1.7.6.3.2 Functionality
The CI502 Bus Module contains 24 I/O channels with the following properties:
● 8 digital configurable inputs/outputs
● 8 digital inputs: 24 VDC
● 8 digital outputs: 24 VDC, 0.5 A max.
The inputs/outputs are electrically isolated from the Ethernet network. There is no potential sep-
aration between the channels. The configuration of the analog inputs/outputs is performed by
software.

1.7.6.3.3 Electrical Connection
The Ethernet bus module CI502-PNIO is plugged on the I/O terminal unit TU507-ETH

munication Interface Modules” on page 145. Properly seat the module and press until it locks in
place. The terminal unit is mounted on a DIN rail or with 2 screws plus the additional accessory
for wall mounting (TA526
Ä
Chapter 1.8.2.4 “TA526 - Wall Mounting Accessory” on page 1152).
The electrical connection of the I/O channels is carried out using the 30 terminals of the I/O ter-
minal unit. I/O modules can be replaced without re-wiring the terminal units.
For a detailed description of the mounting, disassembly and electrical connec-
tion of the module, please refer to the System Assembly, Construction and Con-
nection chapter

The terminals 1.8 and 2.8 as well as 1.9, 2.9 and 3.9 are electrically interconnected within the
terminal unit and have always the same assignment, independent of the inserted module:
